Description

Technical Field

[0001] This utility model relates to the field of seat technology, specifically to a ventilated seat and vehicle. Background Technology

[0002] With the rapid development of the new energy vehicle market, the total penetration rate of new energy vehicle sales in my country reached 47.6% in 2024, and the customer base is showing a clear trend towards younger demographics. Younger users have a higher acceptance of domestic brands and new energy vehicles, are more receptive to intelligent technologies and new trends, and are also increasingly demanding higher quality from their vehicles. Therefore, future vehicle design trends will focus more on creating a pleasant, comfortable, and satisfying in-car environment for consumers. As a crucial component of automotive interiors, the design and performance of new energy vehicle seats directly impact the comfort and safety of passengers, making their importance self-evident.

[0003] Currently, ventilated seats on the market primarily achieve ventilation through the following methods: a ventilation system is installed inside the seat cushion and backrest, using a fan to draw air in and guide it into a ventilation layer within the seat. After flowing within the ventilation layer, the air gradually permeates to the seat surface. The seat cover is typically made of perforated leather, and these perforations allow air to pass through and directly act on the passenger's body, thus achieving the ventilation effect. However, existing ventilated seat designs have some unavoidable drawbacks:

[0004] First, there are negative effects on the muscles: the airflow from ventilated seats blows directly onto areas of the body that bear pressure for extended periods, such as the lower back, back, or buttocks. This continuous airflow can irritate muscles, affecting blood circulation and muscle relaxation, potentially leading to discomfort or even health problems. Second, the direct airflow from ventilated seats can cause discomfort, especially during long journeys, easily leading to fatigue and discomfort. Third, the design of direct airflow onto the body accelerates the accumulation of dust and dirt on the seat surface, increasing the difficulty and frequency of cleaning and thus raising maintenance costs.

[0005] In conclusion, while existing ventilated seat designs have achieved some success in improving passenger comfort, they still have many shortcomings, especially regarding comfort during long journeys, health impacts, and maintenance costs. Therefore, there is an urgent need for a new type of ventilated seat design that can ensure effective ventilation while avoiding the negative effects of direct airflow, thereby improving passenger comfort and reducing maintenance costs. Summary of the Invention

[0006] In view of this, the purpose of this utility model is to provide a ventilated seat and vehicle to solve the negative effects of the air blowing directly onto the human body through the seat body in existing ventilated seats, thereby improving riding comfort and addressing the problem of high maintenance costs.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A ventilated seat includes: a seat body, the seat body having a sealed cavity inside, the sealed cavity being connected to an air inlet channel and an air outlet channel, the air outlet of the air outlet channel being aligned with the rear seat, so that heated or cooled gas flows into the sealed cavity through the air inlet channel to heat up or cool down the seat, and then the gas flows out from the air outlet channel to heat up or cool down the rear seating area.

[0009] Based on the aforementioned technical means, by incorporating a sealed cavity within the seat body for storing hot or cold air, the seat body can be heated and cooled, effectively preventing discomfort caused by hot or cold air blowing directly onto the occupants. This effectively solves the negative impact of existing ventilated seats where air blows directly onto the body, improving ride comfort. The sealed cavity for heating and cooling the seat body effectively reduces the accumulation of dust and dirt on the seat surface, thus lowering maintenance costs. Furthermore, by positioning air vents directly opposite the rear seats, the rear passenger space can be heated and cooled, enhancing rear passenger comfort.

[0010] Preferably, the seat body includes a seat surface layer, and the sealed cavity is formed by the seat surface layer and a sealing component.

[0011] Preferably, the surface material of the seat is silicone leather to improve thermal conductivity.

[0012] Preferably, the sealing component includes a sealing layer and an isolation layer stacked together, the sealing layer being located inside the sealing cavity and the isolation layer being located outside the sealing cavity.

[0013] By setting an isolation layer outside the sealing layer, energy transfer is effectively prevented, enhancing the thermal and sound insulation performance of the sealed cavity. The sealing layer, acting as the inner liner of the sealed cavity, effectively ensures its airtightness.

[0014] Preferably, the sealing layer is a TPU film layer; the insulating layer is a heat-insulating cotton felt layer.

[0015] Preferably, the TPU film layer and the heat-insulating cotton felt layer are laminated under heating and pressurization conditions, and the sealing component is bonded to the seat surface with an adhesive and cured by heating and pressurization to ensure the sealing performance of the sealing cavity.

[0016] Preferably, the seat body further includes a cotton layer, a hard cotton layer, and a foam layer disposed sequentially below the seat surface, wherein the cotton layer, the hard cotton layer, and the foam layer are located within the sealed cavity.

[0017] By placing a cotton layer under the seat surface, wrinkles that would form on the seat surface due to prolonged sitting pressure are effectively prevented. This also increases the softness and comfort of the seat, providing passengers with a more delicate tactile experience. By placing a hard cotton layer under the cotton layer, the seat's support, comfort, breathability, and durability are significantly improved, bringing a better riding experience to passengers.

[0018] Preferably, a temperature controller is provided in the air inlet channel.

[0019] By installing a temperature controller in the air intake duct, the incoming air can be heated or cooled.

[0020] Preferably, the air inlet of the air inlet channel is connected to a fan.

[0021] Preferably, the angle between the air inlet channel and the horizontal line is 120°~140° to ensure that the heated or cooled gas can evenly fill the entire sealed cavity.

[0022] Preferably, the air inlet channel and the air outlet channel are respectively the air inlet pipe and the air outlet pipe, which are injection molded from HDPE material.

[0023] Preferably, the air outlet channel has a first diversion air outlet channel and a second diversion air outlet channel, the air outlet of the first diversion air outlet channel is aligned with the rear seat, and the air outlet of the second diversion air outlet channel is aligned with the fan.

[0024] By setting the air outlet channels as a first and second split air outlet channel, both heating or cooling of the rear passenger space is achieved, and air circulation is realized, thus reducing energy consumption.

[0025] For example, the air outlet of the first diversion air duct is directed towards the feet of the rear seat passengers.

[0026] Preferably, the ventilation area of ​​the first diversion air outlet channel is smaller than the ventilation area of ​​the second diversion air outlet channel.

[0027] By setting the ventilation area of ​​the first split air outlet channel to be smaller than that of the second split air outlet channel, the airflow into the first split air outlet channel is less than that into the second split air outlet channel, thus ensuring that appropriate cool or hot air is blown to the rear passengers and improving comfort.

[0028] Preferably, the air outlet duct is provided with a flow-blocking component at the air inlet.

[0029] Preferably, the flow-blocking component is a flow-blocking rubber sleeve. The flow-blocking rubber sleeve has a cross-shaped cut in the middle to ensure that it can be forced open under certain gas pressure, so as to smoothly send the gas in the sealed cavity into the air outlet channel.

[0030] This utility model also provides a vehicle including the ventilated seat described in this utility model.

[0031] The beneficial effects of this utility model are:

[0032] This utility model of a ventilated seat utilizes a sealed cavity within the seat body to deliver hot or cold air, achieving both heating and cooling functions. This effectively prevents hot or cold air from directly blowing onto the occupants, eliminating the discomfort caused by direct airflow in traditional ventilated seats and significantly improving seating comfort. Furthermore, the sealed cavity design reduces the accumulation of dust and dirt on the seat surface, lowering cleaning and maintenance costs. Simultaneously, air vents in the rear seats further enhance the temperature regulation of the rear passenger space, improving their riding experience. The overall design optimizes seat temperature control performance while balancing comfort and practicality. It has significant potential for widespread application in the field of seat technology.

Detailed Implementation

[0038] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0039] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0040] Numerous details are explored in the following description to provide a more thorough explanation of embodiments of this application; however, it will be apparent to those skilled in the art that embodiments of this application may be implemented without these specific details.

[0041] This utility model aims to disclose a ventilated seat and vehicle to solve the problem that in existing ventilated seats, the air is blown directly through the seat body to the waist, back, or buttocks, which are subjected to pressure for a long time. The continuous airflow can stimulate muscles, affect blood circulation and muscle relaxation, and may lead to discomfort or even negative health effects. It can also solve the problem that if there are holes in the seat body, the frequent airflow will accelerate the accumulation of dust and dirt on the seat surface, increase the difficulty and frequency of cleaning, and thus increase maintenance costs.

[0042] Among them, such as Figures 1 to 4 As shown, a ventilated seat includes: a seat body 1, the seat body 1 having a sealed cavity inside, the sealed cavity being connected to an air inlet channel 2 and an air outlet channel 3, the air outlet of the air outlet channel 3 being directed toward the rear seat, so that heated or cooled gas flows into the sealed cavity through the air inlet channel 2 to heat up or cool down the seat, and then the gas flows out from the air outlet channel 3 to heat up or cool down the rear seating area.

[0043] By embedding a sealed cavity within the seat body to contain hot or cold air, precise temperature regulation of the seat can be achieved. This method effectively prevents hot or cold air from blowing directly onto the occupants, thus reducing discomfort. It solves the problem of traditional ventilated seats, where air blows directly onto the body, significantly improving ride comfort. Furthermore, heating and cooling the seat through the sealed cavity effectively reduces the accumulation of dust and dirt on the seat surface, thereby lowering maintenance costs. Moreover, by specifically targeting the rear seats with air vents, temperature regulation of the rear passenger space is achieved, further enhancing the comfort experience for rear passengers.

[0044] In some embodiments, the seat body 1 includes a seat surface 11, and a sealed cavity is formed by the seat surface 11 and the sealing component 4.

[0045] For example, the seat surface 11 is made of silicone leather to improve thermal conductivity.

[0046] In some embodiments, in order to effectively prevent energy transfer, enhance the thermal insulation and sound insulation performance of the sealed cavity, and ensure the airtightness of the sealed cavity, the sealing component 4 is configured to include a sealing layer 41 and an isolation layer 42 stacked together, with the sealing layer 41 located inside the sealed cavity and the isolation layer 42 located outside the sealed cavity.

[0047] The sealing layer 41 is a TPU film layer, which serves as the inner liner of the sealed cavity and effectively enhances its airtightness. The isolation layer 42 is a thermal insulation felt layer with a thickness of 4mm to 8mm. The thermal insulation felt layer is made of thickened cotton fabric with a multi-layer weaving process. The air layer between its fibers can effectively prevent energy transfer, thereby enhancing thermal insulation and sound insulation performance.

[0048] For example, the TPU film layer and the heat insulation cotton felt layer are laminated under heating and pressure conditions, and the sealing component 4 is bonded to the seat surface layer 11 with an adhesive and cured by heating and pressure to ensure the sealing performance of the sealing cavity.

[0049] In some embodiments, to prevent the seat surface from wrinkling due to prolonged human pressure, and to increase the softness and comfort of the seat and provide passengers with a more delicate touch, the seat body 1 is configured to include a cotton layer 12, a hard cotton layer 13, and a foam cotton layer 14 disposed sequentially below the seat surface, with the cotton layer 12, the hard cotton layer 13, and the foam cotton layer 14 located within a sealed cavity.

[0050] By setting a hard cotton layer 13 under the cotton layer 12, the support, comfort, breathability and durability of the seat are significantly improved, bringing a better riding experience to the passenger.

[0051] The cotton layer 12 is placed close to the bottom of the seat surface to effectively prevent the seat surface 11 from wrinkling due to prolonged sitting pressure from the human body. It also increases the softness and comfort of the seat, providing passengers with a more delicate tactile experience.

[0052] For example, metal powder or carbon fiber is added to the cotton layer 12 to improve thermal conductivity, and the cotton layer 12 itself has good breathability, which can effectively allow hot or cold air to penetrate upward to the seat surface layer 11.

[0053] The rigid cotton layer 13 is a rigid 3D cotton layer. The rigid 3D cotton layer can significantly improve the support, comfort, breathability and durability of the seat, bringing a better riding experience to the passenger. The rigid 3D cotton layer has high breathability and is also the main layer for air flow. It is combined with the bottom foam cotton layer 14 through hot melt composite technology.

[0054] The foam layer 14 is made of polyurethane (PU) foam material, which has good elasticity and breathability, low density and good resilience. At the same time, polyurethane foam has the characteristics of not being easily deformed, wear-resistant, moisture-proof and shockproof, and can meet the needs of different people.

[0055] In some embodiments, in order to effectively heat or cool the air flowing into the air inlet channel 2, a temperature controller 5 is provided in the air inlet channel 2.

[0056] The temperature control switch 8 of the temperature controller 5 is integrated into the seat control panel 9. The temperature control switch 8 can control the rise and fall of the gas temperature flowing into the air intake channel 2 to achieve the temperature desired by the passenger.

[0057] In some embodiments, the air inlet of the air intake duct 2 is connected to a fan 6 to smoothly deliver air from the cabin into the air intake duct 2.

[0058] For example, the angle between the air inlet channel 2 and the horizontal line is 120°~140° to ensure that the heated or cooled gas can evenly fill the entire sealed cavity.

[0059] For example, air inlet channel 2 and air outlet channel 3 are air inlet pipe and air outlet pipe, respectively, and the air inlet pipe and air outlet pipe are injection molded from HDPE material.

[0060] In some embodiments, in order to heat or cool the rear passenger space while also recirculating the gas to reduce energy consumption, the air outlet duct 3 is configured to have a first diversion air outlet duct 31 and a second diversion air outlet duct 32. The air outlet of the first diversion air outlet duct 31 is directed toward the rear seat, and the air outlet of the second diversion air outlet duct 32 is directed toward the fan 6.

[0061] For example, the air outlet of the first diversion air outlet 31 is directed toward the feet of the rear seat passengers.

[0062] In some embodiments, the ventilation area of ​​the first diversion air outlet duct 31 is set to be smaller than the ventilation area of ​​the second diversion air outlet duct 32, so that the air volume flowing into the first diversion air outlet duct 31 is smaller than the air volume of the second diversion air outlet duct 32, thereby further ensuring that suitable cool or hot air is blown to the rear passengers and improving comfort.

[0063] In some embodiments, a flow-blocking component 7 is provided at the air inlet of the air outlet channel 3 to ensure the heating and cooling of the sealed cavity, and to allow the gas to be pushed open after reaching a certain pressure, so as to smoothly send the gas in the sealed cavity into the air outlet channel 3.

[0064] For example, the flow-blocking component 7 is a flow-blocking rubber sleeve. The flow-blocking rubber sleeve has a cross-shaped cut in the middle to ensure that it can be opened by a certain gas pressure, so as to smoothly send the gas in the sealed cavity into the air outlet channel 3.

[0065] The flow-blocking sleeve is made of rubber that is resistant to high and low temperatures, has a certain strength, and good resilience, such as silicone rubber, with a thickness of 2mm to 3mm. The flange of the flow-blocking sleeve is joined to the air outlet duct by heat fusion to ensure connection strength.

[0066] For example, the backrest and seat cushion of the seat body 1 are respectively provided with a sealed cavity, an air inlet channel 2 and an air outlet channel 3, and the air outlet channel 3 of the backrest and the air outlet channel 3 of the seat cushion are connected together.

[0067] In actual use, the aforementioned ventilated seat draws in air from the cabin via the fan 6, allowing the air to flow from the air inlet duct 2 into the temperature controller 5 for cooling or heating. The cooled or heated air is then transported to the sealed cavity via the air inlet duct 2. The cotton layer 12, hard cotton layer 13, and foam layer 14 of the sealed cavity have high breathability and thermal conductivity, allowing hot or cold air to permeate upwards to the seat surface 11, thus heating or cooling the seat body. When the hot or cold air fills the entire sealed cavity, the increased air pressure forces open the flow-blocking component 7 at the air inlet of the air outlet duct 3, allowing some of the hot or cold air to flow through the first branch air outlet duct 31 to the rear seats, thus heating or cooling the rear seats and providing warmth or coolness to the rear passengers' foot areas, improving seating comfort. Another portion of the hot or cold air flows through the second branch air outlet duct 32 to the fan 6, achieving gas recycling.

[0068] In some embodiments, a vehicle is also provided, including the ventilated seat of any of the above embodiments.

[0069] In summary, this ventilated seat, by incorporating a sealed cavity within the seat body to deliver hot or cold air, achieves both heating and cooling functions. This effectively prevents hot or cold air from directly blowing onto the occupants, eliminating the discomfort caused by direct airflow in traditional ventilated seats and significantly improving seating comfort. Furthermore, the sealed cavity design reduces the accumulation of dust and dirt on the seat surface, lowering cleaning and maintenance costs. Simultaneously, by incorporating air vents in the rear seats, temperature regulation of the rear passenger space is further achieved, enhancing the rear passenger experience. The overall design not only optimizes the seat's temperature control performance but also balances comfort and practicality. It has significant potential for widespread application in the field of seat technology.

[0070] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
